New puppy, old member

Hi all
I used this blog 9 years ago and it saved my life with a new lab puppy. I had a lab for 15 years prior to this new pup and it was a struggle at best. My 9 year old lab is the best dog and I have this board to thank. So here I am again. I have a nine week old so I'm a bit rusty. I have questions on food of course. I think I need to post on diet and nutrition? Also my pup is Arlo not Alto. I don't know how to edit user name??
